Answer:

Step-by-step explanation:
a1 = 8
a9 = 56
Using formula for finding nth term of arithmeric sequence

We have to find 24th term, therefore n = 24
is the first term but we are missing d
d is the difference between the two consecutive terms, lets calculate it first
a9 = 56
Using the above given formula for finding d
put n = 9, a9= 56

56 = 8 + 8d
8d = 48
d = 6
Getting back to main part of finding 24th term
n = 24, d = 6, a1 = 8
put values in nth term formula




C2+ 10
Twice = multiply by two
10 more than = add ten
Hope this helps!
Answer:
6.
Step-by-step explanation:
Lucy studies one less (-1) than twice the number of hours a week that rose studies (2 * R), lucy studies 11 hours a week. What we do is add 1 hour to lucy's 11, to get 12, then divide by 2 as lucy studies twice the hours. 12 / 2 = 6.
Answer:
x-int is 3
y-int is -4
Step-by-step explanation:
when x is zero, -9y = 36
y = -4
when y = zero 12x = 36
x = 3
